如何为python的机械化设置超时值？

Answer 1

Alex is correct: mechanize.urlopen takes a timeout argument. Therefore, just insert a number of seconds in floating point : mechanize.urlopen('http://url/', timeout=30.0) .

The background, from the source of mechanize.urlopen :

def urlopen(url, data=None, timeout=_sockettimeout._GLOBAL_DEFAULT_TIMEOUT):
    ...
    return _opener.open(url, data, timeout)

What is mechanize._sockettimeout._GLOBAL_DEFAULT_TIMEOUT you ask? It's just the socket module's setting.

import socket

try:
    _GLOBAL_DEFAULT_TIMEOUT = socket._GLOBAL_DEFAULT_TIMEOUT
except AttributeError:
    _GLOBAL_DEFAULT_TIMEOUT = object()

Answer 2

如果你正在使用Python 2.6或更高版本，以及相应更新的mechanize版本， mechanize.urlopen应该接受一个timeout=...可选参数，这似乎是你正在寻找的。

Answer 3

I believe something along the lines of

mechanize._sockettimeout._GLOBAL_DEFAULT_TIMEOUT = 100

will override the default value Mechanize uses.
